BC Rich platinum strat info,please.

Can anyone tell me anything about my BC rich platinum series strat.The serial # E703872. It is not made of plywood not sure what wood just know it isn't plywood.It is like a pearl white with gotoh tuners the pick ups are HSS not sure what kind. It says it is made in korea on the back of the head stock. From what I have read it should be plywood. I bought it new in about 1989-1990.Maybe a little earlier. It has a 5 way pick up selector one volume and one tone. It also has one small switch that I assume is a coil split. Any help would be greatly appreciated.
